IMPROVEMENT IN OLDER-MILLS.

Specilication forming part of Letters Patent N0. 49,088, dated August 1, 1865.

To all whom it may concern:

Be it known that we, JAMES A. CREVER and FIELDING H. KEENEY, ot'Oincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Mills for Crushing and Expressing the Juice from Fruits, Vegetables, &c. and we do hereby declare the following to be a full, clear, and exact description thereof', reference being had to the accompanying drawings, making part ot' this specification.

Our invention relates to an arrangement of a concave or hollow cylinder in connection with a convex cylinder or roller of somewhat smaller diameter and interior-ly tangential to said concave, with which it meshes and revolves in unison, and the crushing and expressing` actions are performed by and between the mutually-progressing and gradually-converging surfaces of said roller and concave.

Figure l is a perspective view of a mill embodying our improvements. Fig. 2 is a latitudinal section of the same.

A is a frame or stand, supporting at a suitable slope and elevation a circular door, B, having near its lower part numerous apertures, b, for the escape of the expressed juice, and having near its Lipper part an aperture, b', for the escape of pomace.

Journaled in the stand vertically to the slope of the floor B are friction-wheels C, which confine, while permitting the rotation of, a cylinder, D, whose upper end has a bevel-wheel, d, which meshes with a corresponding pinion, E, by which it is rotated.

Journaled in the frame A, so as to be interiorly tangential to the concave or inner surface ot' the cylinder D, is a couver cylinder or roller, F, of somewhat less diameter than the concave D, with which it meshes and revolves by means ot'cogs d" andf.

I is a plate attached to the door B and rising obliquely upward, its edges scraping the sides of both concave and roller.

When designed for expressing the juice of grapes the roller l) may have its periphery clothed with india-rubber or its equivalent, so as to avoid crushingl the seeds and stems.

Operation: The cylinder being set in motion, apples. beets, or other lfruits or vegetables are led into the crescent-formed space Gr, and heilig grasped by the simultaneously progressing and converging surfaces of the roller and the concave, are at the same time fed forward and crushed, so as to express theirjuices, which, desce..ding, pass o.' through the apertures b into a trough or other suitable receptacle, while. the pomace, passing th rough between the roller and the concave, becomes detached by the scraper I and drops ont at the aperture b.

We claim herein as new and ot' our invention- The employment,in a crushing and expressing mill, of a cylindrical concave, D, revolving in partial contact with a smaller and interior cylinder or roller, F, in the manner and forthe objects substantially as set forth.

In testimony ot' which invention we hereunto set our hands.
